Strange question but thought I'd ask. I have a real nice survivor car (66 Coronet 500) but the drivers front seat was too torn to save. I had both front seats recovered so they'd match. The rear seats are excellent and cleaned up almost like new, but have faded some over the years.

Is there a process to take some of the "new" off the the recovered seats to blend with the originals? Wondering if anyone has done this.

I've never heard of it being done, BUT if you want your seat covers to "sunlight fade" subject them to hours & hours of UV light....a tanning booth would be perfect. Remember that UV light is really, really bad for your eyes, so be careful. Also, be careful not to melt the seats if they are vinyl.

I notice your "tag line" about science....you can change the result you show on paper, but you can't change reality....ask me how I know

if you had a good sandblast guy he can age your seats but those colors are dyed so they wont be awesome but if he/she is good you could try. perhaps try your old covers and see. the garment industry regularly media blasts clothes, especially jeans to age them
